G10L 19/02 using spectral analysis, e.g. transform vocoders or subband vocoders
Introduced: January 2000
Full Title
Full titles differ between systems:
Speech or audio signal analysis-synthesis techniques for redundancy reduction, e.g. in vocoders; Coding or decoding of speech or audio signals, using source filter models or psychoacoustic analysis > using spectral analysis, e.g. transform vocoders or subband vocoders
Speech or audio signals analysis-synthesis techniques for redundancy reduction, e.g. in vocoders; Coding or decoding of speech or audio signals, using source filter models or psychoacoustic analysis (in musical instruments G10H) > using spectral analysis, e.g. transform vocoders or subband vocoders
Of 6 combined children, 4 exist in both systems.
2 codes are CPC-only extensions.
1 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 2013.
